So after much searching, I finally broke down and bought underbody protection from Kolchuga, a Ukrainian company. It took about 3 months to arrive, but it was reasonably well protected in transit. I ordered the engine compartment/oil pan/transmission skid plate as well as the center and rear diff plates. They shipped in two “packages” wrapped in bubble wrap with the edges protected by foam padding. Pics below with a gallon jug of rain-x for scale The packages were heavy - about 30 lbs each!
The skid plates are supposed to mount using pre-existing holes on the underside of the Touareg’s frame. It comes with specially welded bolts in an “L” shape that you slot into the holes. You secure the Kolchuga cross-members to these bolts, then bolt the skid plate to the cross member.
Unfortunately, 7 of the 9 holes in the frame were too small for the bolts, and I had to trim the bolts to fit. I don’t know if this will have much of a structural impact on the skid plates in the long term. Seems like it should be okay. But it was very frustrating to cut them with a dremel. It would have been a piece of cake with my angle grinder, but I lent it out...
Supporting the cross-members with a jack made the process much easier. Those L bolts were really finicky.
The rear diff protection doesn’t fit. The leading bolt hole is centered on the skid plate, but the whole in the frame is off-center about about 1 inchto driver/left of centerline, so they don’t align. At some point, I’ll drill a new hole into the skid plate, but for now I’m leaving it off rather than only securing it with two bolts.
